Hello. I am an E28 owner and I am thinking about buying a 1971 3.0CS. I have taken some pics of the car in questions and posted them on a web site. I'd really appreciate it if you could take a look and let me know what you think. also, where are the usual rust places i should check and other things i need to look into.

I might be able to get the car for around $5700US to $6800US. I'd like to know what you think! :)
